Should I accept the Amazon Vine invitation? Did you?

I joined Amazon Vine without any good advice except what Amazon says at

There are thousands of free items you get (up to $300 "free" per day) on Vine, where Amazon sells it to the sellers using this advertising pitch.

Luckily it's easy to get on Amazon Vine if you're detail oriented, which is why I figured most of you will already be on Amazon Vine to advise me.

I picked up already some oscilloscope parts, a DMM, a $100 OBD-II tester, etc., where the only bad thing is you have to order at least 80 items.

Of those 80 items (up to $100 each) you can only order three per day, but they deliver them super fast (by car in fact) up to 10pm every night.

I picked up spark plugs and a serpentine belt and a bunch of the fancy LED light bulbs for the car, and a shovel & small wagon for the yard already.

The deal is you have to keep every item for six months which you have to agree to although you can destroy the item at any time as part of a test.

So I ordered a few screen protectors and destroyed them which was fun! I also ordered ceramic dishes and had fun videotaping their destruction.

Amazon seemed to love the videos as they put my reviews first and they all of a sudden gave me much better stuff (like $100 necklaces for the wife).

When/if I make it to Gold status in six months, they up the ante to an unlimited price per item (like laptops & generators) at 8 items per day.

The main bad thing is that they kick you off the program if you don't get at least 80 items every six months and if you don't review 90% of them.

Have any of you been promoted to Gold or kicked off the Vine program? What is your advice?
